big list of questions heres some basic answers you can use either dino oil or synthetic. syntectic cost more but is more effecient ie better millage both at the diesel pump and oil change intervals. . in the end they cost the same. i use all syntetic in everything. you can change you fuel filter your self it' ain't that hard. one socket and an old rag... . as far as media replacement get the fleet guard from genos they come highly recomened by most readers here... . as always there are many diffrent views on what type of oil to use so make your one decision i use the valvoline synthetic "blue" and change the oil and filters (air and fuel) every 10k cost me arround 100 bucks.
